All skiers have a flex sweetspot: a level that gives them the perfect balance of power and control so they can ski to their limit. The Atomic Redster Club Sport 90 LC ski boot has quite a soft flex for its category, making it perfect if you’re a skier with a medium to light build. It’s then packed with our Atomic racing tech, including our 96mm narrow fit, Progressive Race Shell and Memory Fit, and it comes with a slightly lower cuff height.
